Title: The chemistry of contemporary art: characterization of synthetic resins and study of their aging.

Abstract: A huge number of synthetic materials have been exploited by artists and restorers, and the wide variety of formulations of synthetics resins has allowed their extensive use as paint binders, plastic materials, consolidants, adhesives, coatings and varnishes and many other applications. The use of various and heterogeneous synthetic materials by contemporary artists in paintings, sculptures and installations, and their complex and partially unknown degradation patterns, is at the basis of the complexity of the conservation of contemporary art. The chemical knowledge of synthetic resins used in art and restoration and of their aging process, and the availability of effective analytical methods for their characterization in works of art, are of extreme importance for the proper conservation, to reduce the frequency of restorations, to make them less invasive and reversible while minimizing the risk of damage to the art works. The characterization and aging studies will be performed with the use of analytical techniques such as GC / MS, PY - GC / MS, LC / MS, SEC, FTIR and SEM-EDX. The experimental work will entail three steps:
• selection of materials to be object of the study, on the basis of the state of the art and of specific case studies related to unsolved conservation issues, with particular interest in the latest generation of materials widely used in the cultural heritage as paint and varnishes which, for the most part, have not yet been completely characterized for what concerns their stability;
• chemical analysis and characterization of reference materials and samples from artworks and natural and artificial aging of opportunely prepared and selected materials;
• evaluation of the data to gain a better knowledge of the artworks object of study and of the alteration pathways undergone by synthetic paint materials to contribute to the diagnosis of the state of alteration and to the selection of conservation approaches under a chemical aspects.
